Hanging fitness device for abdominals

ABSTRACT

The present invention is directed to an apparatus for exercising while safely being slightly suspended off the floor and more specifically a arm attachment apparatus for exercising the abdominal muscles of the human body while hanging off the ground. The device, which is movably attached to and detached from an overhead bar, square or rounded, that allows the user to perform a considerable assortment of exercises off of the ground while being safely held by any already existing secured overhead bar.

BACKGROUND OF THE INVENTION

The present invention is directed generally to an exercise apparatus.More particularly, the present invention is directed to an apparatus forexercising on an overhead bar and more specifically an arm attachmentapparatus for exercising the human abdominal muscles.

Exercising or working out can be accomplished in many ways and for avariety of reasons. People exercise to build and shape the body or toachieve general good health and fitness. Exercise routines can be assimple as walking, running or jogging or can be highly involved andstructured to achieve a desired goal.

Gravity training as a form of exercise can be used not only forbodybuilding and toning but also can be used as a aerobic workout. Inthe past, gravity training was typically performed with the use ofweight machines, free weights or on the floor itself. All have theiradvantages and disadvantages.

While the up and down movement of conventional sit-ups has it'sadvantages, such as specifically isolating and targeting a fewmidsection muscles, this movement can cause strain on the lower backmuscles and spine. the positive effect of working your abdominal musclescomes at a price of sacrificing increased strength that relates tomovements found in daily life.

Non impact gravity training, on the other hand, requires less impact onknees, joints and lower back and it tends to promote increased activityof more muscle groups. Non impact gravity training promotes stretchingand relaxing in a way that conventional sit-ups and abdominal machinescannot. With non impact gravity training, less demands are made on thelower back that has to counteract the forward motion of the weightresisted shoulders and chest. With hanging non impact gravity training,safer workouts are accomplished though constant downward lower backstretching and movements.

Abdominal muscles are very important when it come to outward appearanceof the human anatomy. This is the reason why there are so many differentabdominal machines and gadgets for abs on the market today. When aconventional sit-up or a conventional abdominal machine is being used,not only are the abdominal muscles are in at work, but a host of othermuscles are activated to help execute the movement. Most of the timethough these movements, the lower back muscles has to take the stress ofpressing against the hard surface of the floor or seat.

It is apparent that overhead bars and abdominal workouts can complimenteach other. Exercise routines, especially ones that focuses on strengthtraining should include exercises using modalities that helps stretchthe muscles as well. such complimentary use of stretching and gravity isachievable when working out off the floor. However, when it came toworking out the abdominal and midsection in the past. Conventionalsit-ups and conventional abdominal machines were the only practicaloption.

There are seemingly many more knee and leg lift exercises that can beperformed while off of the ground or floor than can be performed whilepressing against the floor. The fact that one cannot eliminate thepressing against the floor without some form of hanging support,prevents the exercise person from benefiting from all the advantagesthat hanging nonimpact gravity workout has to offer.

Conventional abdominal machines are not designed for portability ormobility. Especially the ones that has heavy resistance weights as partof the machine. These machines are very costly and expensive to up keep.These machines are also large and can only be used in large health clubfacilities. Although conventional sit-ups can be performed almostanywhere, there is still the remaining problem of the neck and lowerback constricting and overexerting themselves while lying on the floor.Even while performing leg lifts, lower back stress can easily occur.Also the constant repetitive back and forth movement of the head neckand shoulders causes dizziness and a desire not to continue theexercise. What is needed is a device which would allow the user tocontract their midsection while at the same time stretch their lowerback. This can most effectively be achieved though hanging nonimpactworkout.

The third portion of the safety bar is a rubber tubecovering 3, that envelopes the vertical girder which helps preventfriction. The fourth portion of the safety bar is one transverse memberconnector opening 38, which connects the safety bar to the upper armflatbed platform assembly by way of theses round openings on the sides.

The shape and dimensions of the materials used for the upper arm flatbed platform assembly should be as such as to permit the safety bar 1,to easily fit securely within the opening on the end. The material usedshould be solid, non-bending and should not bend or break under thestress of human weight.

The material used in the description is a 1 and ¼ inch square solidhollow tubing with a 1/16 inch thick wall. The preferable dimensions ofthe flat plate 8, should be four inches long, by 6 inches wide forming arectangular shape, the thickness of the material said here that beingsolid matter steel or aluminum should be that of 1/16th of an inch orgreater.

The upper arm flatbed platform assembly FIG. 4 is L shape in it'sconstruction on the top of the lower beam 5 is attached a flat plate 8.This flat plate serves as support for the arm cushion 9. Under the flatplate are attached four support brackets 6. these brackets serve asadded strength for the flat plate. These said brackets are triangular inshape and are permanently attached on their edges to the side of thelower support beam 5 and to the bottom of the flat plate 8.

Positioned between the top of the flat plate 8 and the bottom of the 2inch thick foam arm cushion 9 is a portion of wood, not shown, which isenveloped by the vinyl covering. This wood is ½ inch in thickness withthe same 4×6 dimensions as the flat plate 8. The woods presence is toserve as an anchoring point for adhesives and/or staples for the vinylcovering of the foam rubber arm cushion 9. This wood portion is also ananchoring point for transverse members to be attached pointed from underthe flat plate 8. This attachment keeps the cushion and covering securedon the flat plate.

FIG. 4 illustrates what is attached at a 90 degree right angle to thelower support beam 5 is a vertical support shaft 10. This said supportshaft connects the upper arm flatbed platform assembly to the handleextender by the use of the removable pen 12. Attached to the bottom ofthe flat plate are two stands 7, preferably made of rubber that serve asfeet, making the entire upper flat bed assembly unit capable of standingup on the floor unassisted. There is envisioned many different ways toattach the rubber feet 7, one is using a liquid adhesive or glue,another is using a transverse member upwards through an opening in thecenter the rubber foot 7, then through an opening in the flat plate 8,and then having it anchored in the wood portion of the arm cushion 9.

FIG. 6 best illustrates the handle extender assembly as constructed inthe shape of an inverted L. It has four distinct parts to it'sconstruction. The first being a vertical insertion girder 13, this beingthe same make up size material as the safety bar as it fits into theother end of the main frame of the upper arm flatbed platform assembly.This vertical girder 13, is preferably made up of 1 inch square solidhollow tubing with a wall thickness of 1/16 of an inch. Second, there isa series of openings 14, on all four sides of the vertical girder 13.The preferred size of the openings are 5/16 of an inch in diameter andspaced in a row of seven one inch apart on all four sides. The purposefor the openings on the handle extender assembly is for the allowance toadjust the distance between the hand grip and the top of the armcushion. This allows for the various lengths of forearms by differentusers.

The third being a hollow horizontal insertion bar 22, that ispermanently attached at a 90 degree right angle at the upper end of thevertical insertion girder 13. It is preferred that the horizontalinsertion bar 22, be of the same material as the vertical bar 13, butwith a round circumference. It is preferred here that the verticalportion of the handle extender assembly can be inserted into the tube ofthe vertical shaft 13, of the upper arm flatbed platform assembly in twodirections. This differing of direction allows for the differing handgrip position the user can assume while using this device.

FIG. 6 illustrates that on top of the horizontal insertion bar, and 1and ¼ of and inches from the corner joint, is a round opening 23,preferably 5/16 of an inch in diameter. This opening is for theallowance for the rod 20, of v spring button 21, that is placed insideof the horizontal insertion bar 22, to protruded through. The fitting ofthe horizontal insertion bar into the hollow grip 15, of the hand gripunit forms the entirety of FIG. 5 The rod and v spring button 21,contracts with moderate hand pressure and retracts by assuming itoriginal shape while holding it's place by pressing against the insidewall of the horizontal insertion bar 22. The shape and diameter of thehorizontal insertion bar 22, is to accommodate the shape of the handgrip portion 15, of the hand grip unit assembly.

FIG. 5 & FIG. 4. will now explain in a different way the relationship ofthe handle extender and the upper arm flat bed platform assembly. Thesquare shape of the handle extender vertical bar tube 13, when insertedinto the square shape of the upper arm flat bed platform vertical shaft10, achieves a more stable unit of strength as refers to side to sidemovement. This being said the relationship of these parts allows for aworking parallel alignment with each other and a working perpendicularalignment with each other. while not compromising the integrity of it'ssupport and strength.

FIG. 6 illustrates the hand grip unit as described here is in the shapeof an inverted 7 it construction has three different angles and fivedistinct portions to it. It should be made of a hard sturdy materialthat does not bend or break while under stress of holding human weight.Preferably metal, aluminum, or hard plastic resin mold. The horizontalsection 15, should be hollow and have a round circumference preferably 1and ¼ inches in diameter and 8 inches in length On the top of the roundhand grip length is an opening 25, preferably 5/16 of and inch indiameter, this opening 25, should be 1 and ¼ inches from the end of thegrip. The hand grip has a rubber or vinyl covering 26, which reducesfriction to the palms of the hands. On one end of the grip there is a 3inch spacing girder 16, attached at a 90 degree right angle, the purposeof this spacing girder 16, is for the allowance of space between theusers fingers and the existing overhead bar. Attached to the 3 inchvertical spacing girder 16, is another 3 inch spacing girder 17, angledat a right 45 degree angle, back toward the center of the hand grip.This spacing girder 17, allows for displacement and proper balancewhereby user fingers are always positioned directly under the existingoverhead bar. This girder 17, should prevent the device from tippingfrom right to left, or from front to back while in use. The finalextension 18, is preferably 8 inches long and is attached at a left 45degree angle. This top extension 18, when attached to the rest of theassembly should be perpendicular with the hand grip portion 15, of theassembly, thereby forming the inverted 7 shape. This top girders purposeis when it is applied through the back shaft 34, of the top hook andsecured by removable pen 41, is to accommodate various heights of theusers and for various heights of existing overhead bars. At the open endof the 8 inch long round solid hollow tubing of the hand grip unit iscut a 1 and ¼ inch wide, 1 inch long opening 24, on the bottom half ofthe tube. This opening is so that when the round insertion bar of thehandle extender slides into the hand grip, the end of the hand grip andthe back edge of the handle extender are flush and on the same plane.

FIG. 7 illustrates that the top hook is essentially a three sided platethat connects to the hand grip unit assembly. and clamps over and on toa existing overhead bar. The material used should be as such that itdoes not bend or break while under stress of a large humans weight. Thisplate should have a thickness equal or greater to the thickness used forthe hollow tubing for the hand grip unit. Of the three sides of thisunit, the top horizontal side 31, can have a width of up to 8 incheswide and a depth of up to 5 inches. It's important to note that theoverall exact proportions of the top side 31, can be determined by theavailability of existing overhead bars and structures that are on themarket and that are being used today. As illustrated in FIG. 7, the topside 31, of the hook has two elongated openings 32, that are used astracking for the push plate 36. These openings 32, are also used for thepurpose of connecting and holding the push plate to the top side of thehook. This is achieved by utilizing a wide head transverse members 27,placed through each elongated openings 32, and then are connected tofemale transverse members 37, permanently attached to the top of thepush plate 36. The wide head of the transverse member 27, and rubberwashers 39, are wider than the width of the elongated openings 32,thereby allowing push plate 36, not to fall out of the top hookassembly. The front face of the top hook 30, has a preferable depth of 3inches. The front face has one opening in the center. Permanentlyattached directly over the opening is a female transverse member 29. Thefemale transverse member 29, which serves as a connector guide for thelarge transverse tightener 28. This transverse tightener 28, whentwisted in and through the frontal female transverse member 29, pressesthe push plate 36, against the overhead bar. The push plate 36, clampsdown on and secures the top hook assembly onto the users desiredlocation on the bar. The push plate 36, and all inside walls of the tophook is lined with a thin sheet of rubber as to allow for added frictionand for no scratching of the surface of the overhead bar.

FIG. 7 illustrates that the back side of the top hook 33, has the sameshape and dimensions as the front side 30. Located on the back side ofthe top hook is the receiving shaft 34, for the top girder 18, of thehand grip assembly. The preferred size of the shaft 34, should be thatof 1 and ¼ inch wide or that size that matches the width of the upperarm platform assembly's tubing 10. The top hook shaft 34, should have alength of 3 inches long and is permanently attached to top hookassembly. The ends must run in a north/south direction. Positioned onthe top hook shaft sides are two round openings 35, that serve asconnector points for the devices second removable pen or rod 41, andwhich can be attached by a cord 40, to the back side of the top hook 33.
